This is a wonderful chakra meditation to do to reconnect and recharge. It takes between 20-30 mins and you can do it by yourself in the comfort of your home. All you need is to print out the guidelines, a bit of imagination and a quiet space.
A fundamental of meditation is the ability to allow the body to deeply relax. Obviously if the position we are meditating in soon becomes uncomfortable or painful for the body, such relaxation will be harder to develop.
